Be it known that we, JOHN M. SPEAR and WINNIER. STRAW, ofllainfieldfln the county ofWausharaand-State of Wisconsin, have Pipc-Fastcnings, of which the-following is a f uli, clear, and exact description. f

The purpose of this inventionis to provide superior means for permitting adjustment thimbles, elbows,

of the diametersof pipes,

and the like, so that they may be readily made to .fit the parts with which they are to .be used.

' This'specilieation is theIdisclosure ofse'veral forms, of the invention, while the claims define tlie actual scope thereof. 1

Reference is to be had to the accompanying drawing forming a part of this specification,

in which similar cate corresponding parts in all the views. Figure 1 isan elevation of our invention with part of the pipe broken away.

' the point 7.

According to ourfinvention', as shown in Figs. l. and 2,tl1 e pipe 5 is split longitudinally and has lap Sformed on one edge, such lap terminating'short of the length of the pipe at The other edge of the pipe is formed with an inward and laterally turned lap (3, locked with the lap Sand extending throughout the length of the pipe. Throughout the length of the lap 8'tlie two edges of the pipe are fastened securely together by rivets. The end of the pipe at which the lap 8 terminates is arranged to be expanded or euntractedat will to fit a second pipe received in the first. liy cutting away the under lap at the point 7 the upper lap will noteugage the under lap, and thus the free sliding movement of 'the two edges of the pipe over each other is permitted at one end of the pipe.

. Fastened to the respective edges of the pipe v eontractingthe diameter of the pipe.

be seen j the lap useful Improvements in claim as new and characters-of referenoe'indi- Fig. 2 is- -Fig. 3 issecond pipe may pipe.

"Fig. 3 show's the invention applied to an [elbow-piped, in which the pipe has its edge.-

joined by rivets 6 instead of a seam. The end of the pipe [to be expanded or contracted is notfastened by. rivets, 'butis provided with lugs 9;, sin'1ilar to the lugs 9,and provided with ascrew 10 for operating as the screw 10, pl:- viousl y described.

Fig.4 shows a thiinble 5,in which the edges at the upper'end of the thimble are joined by a rivet'ti. The lower end of the thimble has lugs 9 attached thereto, and these lugs work with a screw 1O or in the manner pneviously "described.

Having thus described our invention, we desire to sccureby eis Patent- 1..The combination of a pipe split lougi tudinally and having one of its longitudinal edges turned outward and laterally to form a lap, and having its other longitudinal edge turned inward and laterally to form asccond lap; such laps being interengaged with each other,1'astenings applied to such laps throughout part of the length of the pipe to securely join the edges of the pipe at such part a...

fastenings leaving the. edges at one end of the pipe free, and means mounted at such end of the pipe and connected with the two partsthereof by which to relatively more the same, and adjust the diameter of the pipe.

2. The combination of a pipe split longitie dinally and having a part'of one edge formed with a lap turned outward and laterally and extending a part of thclength of the pipe, the

pipe having at its other longitudinal edge a lap "extended inward and laterally through"- out the length of the pipe, the laps belngil'b tel-engaged and the pipe having its side edges fastened rigidly together throughout the length of the first-named lap, leaving the edges at one end of the pipe free, and means located at such end of the pipe and connect ed with the two parts thereof, by which to relatively move the same, and adjust the diameter oi the pipe.
